Compares two expressions for greater than or equal (a comparison operator).

Transact-SQL syntax conventions

Syntax

expression >= expression

Arguments

expression
Is any valid expression. Both expressions must have implicitly convertible data types. The conversion depends on the rules of data type precedence.

Result Types

Boolean

Remarks

When you compare nonnull expressions, the result is TRUE if the left operand has a greater or equal value than the right operand; otherwise, the result is FALSE.

Unlike the = (equality) comparison operator, the result of the >= comparison of two NULL values does not depend on the ANSI_NULLS setting.

Examples

A. Using >= in a simple query

The following example returns all rows in the HumanResources.Department table that have a value in DepartmentID that is greater than or equal to the value 13.

-- Uses AdventureWorks  
  
SELECT DepartmentID, Name  
FROM HumanResources.Department  
WHERE DepartmentID >= 13  
ORDER BY DepartmentID;

Here's the result set.

DepartmentID Name  
------------ --------------------------------------------------  
13           Quality Assurance  
14           Facilities and Maintenance  
15           Shipping and Receiving  
16           Executive  
  
(4 row(s) affected)
